Description

Broom friction

The invention relates to a partition wall with at least one profile stand of the type specified in the preamble of claim 1. Wall panels, cabinet elements, doors and windows for partition walls, wall cladding and cupboard walls can be attached to the profile stands.

A partition wall of this type is known, the profile supports of which consist of two rolled T-profiles, which are connected to one another in their web area by means of connecting straps to form a double T-profile by means of in-line welding. The connecting straps are arranged at a distance from one another and thus form through openings for the suspension of horizontal

IS zontal spacer profiles. To hang shelf brackets, individual connecting brackets must be replaced with spacer brackets with open-edge recesses, in accordance with the desired grid for the shelf walls. This method of production has proven to be quite complex and expensive. During assembly, the familiar panels are lined up with the uprights using the tongue and groove principle. This does have the advantage of guaranteed sound insulation and joint accuracy, as well as floor-to-ceiling support. A major disadvantage of this construction, however, is that individual panels cannot be replaced without at least part of the row being dismantled.

The invention is based on the object of improving the known partition wall of the type specified at the outset in such a way that it can be produced simply and inexpensively in as

can be manufactured in just a few process steps and that increased flexibility is also ensured with regard to the adjustability and interchangeability of individual panels and shelves while ensuring sufficient sound and fire insulation in the hanging area.

To solve this problem, the features specified in patent claims 1, 20 and 23 are proposed. Further advantageous embodiments and developments of the partition wall according to the invention emerge from the subclaims.

The profile stand used to produce the partition wall according to the invention is designed as a one-piece component, on which all provisions for hanging the wall panels, wall coverings, cabinet elements and for insulation against the passage of sound and fire are made. The profile stand essentially has the shape of a double-T profile, the holding legs of which are connected in pairs in one piece by the hollow chamber boundary wall arranged between them, with further hollow chamber boundary walls arranged on the folding strips of the holding legs. Two of the boundary walls belonging to opposite holding legs are connected in one piece to form the connecting web, while the boundary walls belonging to the other two holding legs have a free edge that rests against the adjacent boundary wall, including the hollow chamber.

According to an advantageous embodiment of the invention, the hollow chamber extends into the area of the holding legs and is limited at the rear by the folding strips.

According to a preferred embodiment of the invention, the connecting web has a crank in the area between the two hollow chambers/ against whose outer flanks, which form an undercut, the edges of the adjacent edge strips lie flat, creating a positive connection.

Advantageously, the holding legs and the associated folding strips of the profile stand have punched and thus exactly overlapping, preferably downwardly tapering hanging slots for hanging elements arranged on the wall elements. In the free area of the connecting web of the profile stand between the hollow chambers, additional punched through holes for assembly purposes.

The profile stands according to the invention are advantageously manufactured as a one-piece rolled profile made of sheet steel. For this purpose, in a first process step The grid openings for the shelf brackets and the through holes in the web area are punched out of a one-piece strip material made of sheet metal. In a second process step, the strip material is fed to a set of bending rollers to produce the rolled profile, whereby the strip material can be cut to length before or after the bending process. The hanging slots for the wall panels, which are designed as double punches, are preferably made in a third process step from the overlapping holding legs and folding strips. of the erected rolled profile.

In order to avoid the double punchings that have to be made in the third, rather complex process step, it is proposed according to an advantageous embodiment of the invention that the wall and/or cabinet elements carry at least one mounting bracket, one leg of which is attached to the rear broad side surface, which has a rear-facing insertion leg that is essentially flush with the joint-side front surface of the wall and/or cabinet element in question. Due to these precautions, the two facing insertion legs of two adjacent wall and/or cabinet elements can be inserted together into one of the grid openings of the profile stand leading to the hollow chamber. In order to anchor the To ensure the insertion legs in the grid elements, these have bends directed towards each other in pairs at their rear ends, while in the joint area between the insertion legs a spacer element is inserted which is engaged behind by the bends when assembled. can be inserted into the grid opening and anchored to the edge of the opening. The anchoring is carried out in a practical way by the spacer element having an open-edge recess that encompasses the lower edge of the grid opening. A corresponding result can also be achieved by This can be achieved by having the insertion leg with an open-edge recess that encompasses the lower edge of the grid opening. In order to be able to use one and the same insertion leg on both sides, one open-edge recess pointing downwards and one pointing upwards can be provided. be.

The hollow chambers intended for sound and fire protection must be designed in such a way that

the hanging elements or hanging legs fit into them. Their width can extend into the area of the holding legs and be limited at the back by the folding strips. 5

In order to prevent the installed wall panels or wall cabinets from being accidentally lifted out, a locking device can be arranged in at least one grid opening and/or one hanging slot, in which the hanging element or the hanging leg of the wall and/or cabinet element can be locked.
